Letterboxd - Count films by director (updated)

A small utility script that, given an exported Letterboxd user data file, outputs a text file with directors grouped by the count of films directed by them that the user has watched:

15 films (1 director):
Krzysztof Kieślowski

10 films (1 director):
Lars von Trier

8 films (3 directors):
Wes Anderson
Stanley Kubrick
Sion Sono

(and so on, and so forth...)

The script gets the director(s) of a film by scraping its Letterboxd page. It stores (film, director) pairs in a cache file (cache.csv by default) to avoid unnecessary requests.

Usage

1. Export your user data from Letterboxd settings page.
2. Run the script: python letterboxd_count_by_director.py path/to/downloaded_data_file.zip.
3. See output.txt for results.
